On iPhone 4 with iOS 7, it is working. But on iPhone 6 with iOS 9 it doesn't give me carrier details: carrier title is not correctly shown (just says "Carrier"), and signal strength shows -113dBm. Can this be fixed, or have Apple done what they always do and restrict access to all the useful system data? ### 1/5 — Levels don't change *2015-11-05* Took samples at 4 different places, 1 of which there was no service. No variation in reported signal level. Ping times seemed accurate. ### 1/5 — No support since iOS7 *2015-10-10* Used to work quite well but signal strength stopped working since iOS8. Any chance of an update ### 1/5 — Doesn't work with cellular so no use. *2015-08-24* Doesn't work with cellular so no use. ### 1/5 — They need to update it *2015-08-08* Does not work with 8.4. Too bad it was great to verify cell signal level. No it is just another useless app. Please fix it ### 1/5 — Phone signal always 0% *2015-07-28* Have run this app several times in several different situations/locations and every time the stated signal strength is 0%. Therefore a waste of time. ### 2/5 — Broken by iOS 8.4? *2015-07-16* Have been using this app to measure the frankly shockingly bad signal strength I get from O2 at home. Has been working fine until I upgraded my iPhone 5 from iOS 7.1.2 to 8.4. Now, the signal strength always shows 0% -113.0 dBm. Latency appears to be working. ### 1/5 — Could of been a nice app *2015-07-10* The RSSI part does not work The value of the latency would need to be verified Too bad could of been a useful app ### 3/5 — Not working on IOS 8.4 *2015-07-09* This was a very useful app. Sadly the "Phone Signal" reading no longer updates after upgrading my 5s to 8.4. ### 1/5 — Stuck on 113db ! *2015-05-27* No matter what i do or where i go this app shows my iPhone 5 cell signal to be 113db and it never changes even when the signal bars go up and down on my phone. I've tried auto refresh and manual refresh. Just sticks on 113db. Pretty bad considering ! ### 1/5 — Was great no doesn't work😢 *2015-04-20* This app was fantastic for checking out my Willson cellphone amplifier. But now only shows "0" phone signal on 4G, even when I have 5 bars near a known tower. Trashed it & download it again. Still nothing but zeroes. Wish it worked. ### 1/5 — Instructions & bug fix required *2015-02-10* Unfortunately this did not provide strength of wifi signal as stated in description (wanted to check signal in various locations including garden) & the automatic updates continued even when disabled. Also had no instructions on how to interpret data provided so after 30 mins deleted app. Maybe just me but I don't think it does what it's supposed to do. ### 1/5 — Expected what was described got less *2014-05-25* As of May 25, 2014 this app has an inaccurate description and screenshots. You cannot control the background process nor can you monitor your wifi latency. If you are Looking for a utility to test your wifi network this is NOT it ### 4/5 — It's a nice start *2014-05-21* Could it show channel number and signal strength for wifi please. ## Most critical reviews (10 lowest-rated) ### 1/5 — Vanished = NO SUPPORT OR UPDATES *2018-03-04* This developer seems to have vanished like so many apple developers lately ### 1/5 — Useless app. Has not updated in two years *2017-11-20* I have been holding out for this app for awhile now hoping that they would update. We used to use it to check signal strength (cellular dBm readings) for quite awhile... They have not and probably will not update. Don't download. ### 1/5 — Doesn't display active signal strength *2017-01-14* Seems to just be a static display of cell signal: 0% and -113 dB for both iPhone and iPad. ### 1/5 — Doesn't show any more than phone already has *2016-09-23* Signal strength is exactly what my phone has so it is just re-reporting that info. Pointless ### 1/5 — Field Tester no workie *2016-04-21* The field strength sits at "-115dB" all the time. I even tried reloading it but no luck. The latency reading does seem to work however. Since the creator hasn't bothered to fix it for at least 6 months I'd find another app. ### 1/5 — Reinstalled twice; not working. *2016-04-04* The WiFi meter was stuck on 113dMmW. Pretty useless really. ### 1/5 — Shame about the signal strength *2016-03-01* I think this would be a great app if it worked. The signal strength never moves, 0%. The ping responds and gives some info. Perhaps it works on some phones but not my 6. Hope they fix it soon. ### 1/5 — UPDATE THE APP!!! *2016-01-14* Since recent iOS software updates, this app does not work. This was the best tool for reading signals. Now it's. Worthless app. ### 1/5 — Cell Signal always displays 0% *2015-12-26* Unfortunately this app doesn't do the simple functions advertised as the phone signal always displays 0%. However the latency value is usually about 260 ms and does change, but I need the phone signal level. I have an iPhone 6s Plus on the Verizon network and have tested at multiple locations with different signal strengths. Very disappointed... ### 1/5 — App no longer works for cellular dbm *2015-11-11* App used to be great. Cell dbm quit working. Deleted the App and reloaded and still doesn't work... ## Most praised reviews (10 highest-rated) ### 5/5 — Update? *2018-04-02* Can’t use this app on iOS 11, please release update version ### 5/5 — Works fantastic! *2015-06-18* All I want is to see the network db strength. It works, thats it! ### 5/5 — Perfect. Wilson electronics told me about this and this works perfectly. Nice job app developers!! *2014-10-30* Very happy with it. ### 5/5 — Cell signal level is accurate *2014-09-21* Verified using Apple field test app. ### 5/5 — The best *2014-01-16* As above ### 5/5 — Good & Accurate *2013-11-22* Works fine. No bugs. ### 5/5 — Very useful *2013-08-10* Helped me sort out a problem with a carrier when one of the local masts developed a problem. I would happily pay for this utility. ### 5/5 — Great! *2013-07-23* App works just as described. Simple to use without unnecessary baggage. No bugs to report! ### 5/5 — Really helpful app *2013-01-17* Does exactly what it says ### 5/5 — Simple *2013-01-17* Useful app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
